Setting up an exchange 2010 CAS array
What's the best way of doing it?
Essentially, I've inherited an exchange setup where thousands of staff and student outlook profiles are set to connect directly a single exchange CAS server (as opposed to via a CNAME) and no CAS array currently exists. I'm planning on creating an exchange CAS array this summer, but this obviously means that I either need to 1. create a script to modify all outlook profiles to connect to the CAS array as opposed to the CAS server directly (and as many of these have additional mailboxes and other custom settings, this may be more work than it's worth) or rename the existing CAS server to something else, and call the CAS array what the CAS server was originally called.
Has anyone done this before?
